XOR

Feature Description

Removes the common parts of two or more objects, while merging the remaining parts into a single object.

Various scenarios may occur during XOR operations, which are explained below:

  • If input objects intersect only at points, they will be merged into a complex object (e.g., generating a complex polygon object with two sub-objects as shown below).
  • If input objects intersect only along lines, their adjacent edges will disappear and merge into a simple object.
  • If input objects intersect pairwise on surfaces without overlapping, their intersecting areas will be removed and merged into a complex object (e.g., generating a complex polygon object with two sub-objects as shown below).
  • If input objects consecutively intersect on surfaces without pairwise overlapping areas, they will merge into a simple polygon object.
  • If input objects completely overlap, all participating objects will be deleted.
  • If input objects do not intersect, a complex object will be generated (e.g., generating a complex polygon object with two sub-objects as shown below).

Feature Entry

  • Features tab -> Feature Editing group -> XOR button.

Steps

  1. With the layer editable, select two or multiple objects.
  2. In the Gallery control of the Features tab's Feature Editing group, click the XOR button to open the XOR dialog.
  3. In the dialog, specify objects to retain. For parameter descriptions in attribute processing dialog after XOR operation, refer to Attribute Processing Dialog Description.
  4. Click OK to complete the XOR operation.
